No, animal cell lack chlorophyll as they are non-photosynthetic and heterotrophs, which relayo0n plants and other organisms for their food.... View Article
Yes. Flagella are present in both Gram-positive and Gram-negative bacteria. Bacterial flagella are microscopic coiled, hair-like structures,... View Article
No. There are no living cells that lack membrane. The cell membrane is the outermost covering of cells. It is a semi-permeable membrane, which... View Article
Ribosomes are present in the cytoplasm either freely or attached to the rough endoplasmic reticulum. Ribosomes are synthesised and assembled in... View Article
The process of DNA replication always starts from the 5' to 3' direction because the nucleotides are added to the 3' end of a polynucleotide... View Article
DNA was originally called nuclein because for the first time Friedrich Miescher in the year 1869 he identified and isolated DNA from the nuclei... View Article
Under a microscope, the double-helix structure of DNA can be clearly examined. DNA - Deoxyribonucleic Acid can be easily seen through the naked... View Article
Cheek cells are used for DNA extraction because these cells contain a nucleus and other organelles within enclosed in a membrane. Explore More:... View Article
During the extraction of DNA from the cell, isopropanol is added, which helps in the precipitation of nucleic acids. Explore More: Isolation DNA... View Article
PCR technique is based on the enzymatic replication of DNA. In the PCR technique, thermostable DNA Polymerase is used, because it does not... View Article
Double-stranded RNA is more stable than DNA because DNA contains one less hydroxyl group than RNA’s ribose. Explore More: Difference between DNA... View Article
DNA replication can be unidirectional or bidirectional. In bidirectional, none of the two ends will be stationary and both will be moving.... View Article
DNA is insoluble in alcohol because alcohol increases the concentration of DNA. DNA is polar due to its highly charged phosphate and alcohol are... View Article
RNA primers are necessary for the process of DNA replication because these primers are synthesized by primase, which are complementary to DNA... View Article
